Embodiment
In the multi-link scene of many interfaces, LMA need come the control flows migration according to the real-time connection status (like the activation and the off-state of interface) of the many interfaces in terminal.When new interface was connected to network, LMA was according to real-time Interface status, with the service flow transfer that exists and be more suitable for new interface to new interface; When interface deviated from network when (as connect breaking off), LMA need connect the state that breaks off according to interface, the work flow on this interface is moved to activate available interface.In this case, the aforesaid operations process of LMA just need be the basis with the Business Stream strategy, and this Business Stream strategy needs and terminal synchronizes.
In the multi-link scene of many interfaces, when MN switches,, need before and after switching and between access device, set up bidirectional tunnel in order to promote performance of handoffs (message dropping and handover delay when switching) as reducing between different access networks, be used for the tunnel transmission message.In addition, before and after switching, also need exchange some parameters between the access device, be used to assist the completion of quick and smooth handoff procedure.So, need on server, write down the multi-link real-time position information of many interfaces, like access point (AP, Access Point) ID, access network element ID etc.), be used for access device to obtain address each other, accomplish and to be used to assist the information interaction switched.
In practical application; Can be as shown in Figure 2, in many interfaces multiconnection network, dispose many interfaces multiple access server, this many interfaces multiple access server can link to each other with the anchor point network element; Can also link to each other with access network elements such as access point, access devices, can also link to each other with terminals such as MN.
Terminal such as MN or access network element can be reported the state information (like the interface status information at terminal, positional information etc.) at terminal to many interfaces multiple access server.The anchor point network element can obtain above-mentioned information from many interfaces multiple access server, to trigger the mobility management process (like stream migration or the quick switching of execution etc.) to the terminal.
And access network elements such as access point, access device can be to the load information of many interfaces multiple access server report access network.The anchor point network element can obtain above-mentioned information from many interfaces multiple access server, to trigger the mobility management process (like stream migration or the quick switching of execution etc.) to the terminal.
In addition, the terminal can also obtain the Business Stream policy information from many interfaces multiple access server through the request of sending, and carrying out the selection of interface, or the migration of Business Stream between distinct interface, or is characterized as the suitable access technology of service selection according to Business Stream.In like manner, the anchor point network element also can obtain the Business Stream policy information from many interfaces multiple access server, and in view of the above better mobile management is carried out at the terminal.
In general; Can in many interfaces multiconnection network, dispose many interfaces multiple access server; By many interfaces multiple access server from the terminal and/or access network element obtain location information of terminals, interface status information; The load informations of access network etc. are to trigger the mobility management process (like stream migration or the quick switching of execution etc.) to the terminal.And, can also be with above-mentioned information synchronization to anchor point network element, access network element.
When carrying out interface status information report flow process as shown in Figure 3, the interface status information of MN is reported flow process and can be initiated by terminal or access network element, Interface status is updated to many interfaces multiple access server.Said access network element can be access point, like BS, AP, eNodeB etc. and access device, like access controller (AC, Access Controller), gateway (S-GW, Serving GateWay) etc.
Among Fig. 3, the renewal of MN interface status information can be initiated by the terminal, like step 1, shown in 2.MN uses connecting interface, initiates interface status information to many interfaces multiple access server and upgrades request.
For example, MN has two interfaces simultaneously: cellular interface If1 and WLAN interface If2.MN can use current connecting interface If1 to report interface status information, the i.e. current interface message of interface If1 and If2 to many interfaces multiple access server.Comprise in the interface status information MN_ID (sign), access technology type, Interface status (radio signal quality is strong/radio signal quality is poor/do not have connect), information such as interface ID.
Many interfaces multiple access server upgrades the information in the request according to the interface status information received, for MN creates or upgrades the state information when front port.Interface status comprises:
The interface wireless signal quality is strong: when interface signal intensity was higher than one section duration of certain threshold value, the wireless quality of eating dishes without rice or wine was good.
The interface wireless poor signal quality: when interface signal intensity was lower than one section duration of certain threshold value, the wireless quality of eating dishes without rice or wine was poor, is inappropriate for communication.Should use usable interface transmission interface state information updating request interface multiple access server at the most this moment.
Interface does not have connection: have no signal strength signal intensity.Should use the interface multiple access server at the most of connecting interface transmission interface state information updating request this moment.
Need to prove that above-mentioned statement is a kind of concrete classification form, Interface status also can be divided into and be fit to communication and be not suitable for communicating by letter etc.Interface status in the practical application can be according to the divisions such as demand of actual application environment, operator.
The renewal of MN interface status information also can be initiated by access network element, like step 3, shown in 4.If access device such as AC, S-GW is known the state of the current institute of MN connecting interface, then can the request of transmission interface state information updating interface multiple access server at the most, upgrade in the request and comprise information such as MN_ID, access technology type, Interface status, interface ID.
Access point can be known the current Interface status of MN in the interface access network process, as: AP detects through specific access technology, will inform access device through the MN Interface status that detection is known.Said access point can be evolved base station (eNodeB, Evolved Node B), WALN AP etc., and said access device can be AC, S-GW etc.
Access point can be known the Interface status of MN through two layers of detection or other mechanism, as: in some access technology, access point E-Packets to the terminal, can receive two layers of acknowledge message of self terminal corresponding interface.If access point is after E-Packeting, do not receive two layers of acknowledge message of self terminal in the certain time length yet, think that then this interface loses connection.
Many interfaces multiple access server upgrades request according to the interface status information that access network sends, for MN creates or upgrades the state information when front port.
Many interfaces multiple access server maintenance MN is when the state information of front port.
Like step 5,6, shown in 7, after the current interface message of MN was upgraded, many interfaces multiple access server can respond the interface status information request message of anchor point network element, sent corresponding interface status information to anchor point network element; Also can initiatively send interface status information to the anchor point network element after the renewal.
Particularly, step 5: the active of anchor point network element is to the interface status information of many interfaces multiple access server active request mobile node;
Step 6: the mobile node interface status information that many interfaces multiple access server response anchor point network element is asked;
Step 7: in addition, interface status information to the anchor point network element that many interfaces multiple access server also can the active push mobile node;
For example, anchor point can carry out the decision-making of stream migration according to the state information when front port.Service flow transfer to available connecting interface not having on connection or the poor signal quality interface guarantees not interrupting of data flow, ensures user experience.
When carrying out positional information report flow process as shown in Figure 4, the positional information of MN can be made up of geographical location information and the corresponding network location information of MN interface.Wherein,
Address location information: longitude and latitude;
Network location information: access network identifier, public land mobile network (PLMN that connecting interface is corresponding; Public Land Mobile Network) ID or service set (SSID; Service Set Identifier) or Network Access Point (NAP, Network Access Point) ID, the access network element ID that is connected or IP address.
The renewal of MN positional information can be initiated by terminal or access network element (like AC, S-GW etc.) equally, to upgrade the MN positional information on many interfaces multiple access server.
The renewal of MN positional information can be initiated by the terminal, like step 1, shown in 2.MN uses connecting interface, sends the request of MN updating location information to many interfaces multiple access server.
For example, MN has two interfaces simultaneously, cellular interface If1 and WLAN interface If2.The positional information that MN can use current connecting interface If1 to report the current connecting interface of MN to many interfaces multiple access server, the just positional information of interface If1.
Many interfaces multiple access server is created or upgrades the positional information of current connecting interface according to the information in the request of MN updating location information for MN.
The MN positional information also can be initiated by access network element, like step 3, shown in 4.If access device such as AC, S-GW is known the positional information of the current connecting interface of MN, then can send the request of MN updating location information to many interfaces multiple access server, comprise MN_ID, access technology type, interface ID, positional information etc. in this renewal request.
Access device is known the MN positional information through relational approach, as: through the specific mechanism of relevant access network, obtain the current geographical location information in terminal.
Can in the interface access network process, know the network location information of current connecting interface, as: access point is informed the positional information of the current connecting interface of access device MN.
Many interfaces multiple access server is that MN creates or renewal MN positional information according to the MN updating location information request of the current connecting interface of access network element transmission.
Many interfaces multiple access server maintenance MN positional information.
Like step 5,6, shown in 7, after the current interface message of MN was upgraded, many interfaces multiple access server can respond the interface position information request of switching preceding/network element devices such as back access network element, sends corresponding interface position information to related network elements; The interface position information after the renewal of also can initiatively sending access network element or switch network element devices such as back access network element before switch.
Particularly, step 5: the access network element active is to the interface position information of many interfaces multiple access server requests mobile node;
Step 6: the mobile node interface position information that many interfaces multiple access server response access network element is asked;
Step 7: in addition, many interfaces multiple access server also can initiatively push the interface position information of mobile node to access network element.
For example, MN moves, and causes MN the past access network element to switch to new access network element (can be the switching of access technology of the same race, also can be the switching of xenogenesis access technology).Preceding access network element can obtain the IP address of new access network element from many interfaces multiple access server, the IP address of access network element before new access network element also can obtain from many interfaces multiple access server, thereby the completion of assistance quick and smooth switching.
When carrying out access network load information report flow process as shown in Figure 5; Access network element can be to many interfaces multiple access server announcement access network load information; Many interfaces multiple access server maintenance access network load information, this load information can be that index is created with the access network element.The notice of offered load can directly be reported through access point, also can report through access device.Said access device can be S-GW, AC, evolution packet data gateway (ePDG, Evolved Packet Data Gateway) etc.
In the step 1,2, access point is directly notified self current network load condition; Many interfaces multiple access server is created or is upgraded current offered load situation;
In the step 3,4, access point is reported self current access network load information to access device, and after access device was received the wireless network load information, the offered load situation of comprehensively self knowing was again sent offered load and notified interface multiple access server at the most; Many interfaces multiple access server is created or is upgraded current offered load situation;
In the step 5,6, the anchor point network element is initiatively to the current access network load information of many interface servers of multiple access request;
In the step 7, many interfaces multiple access server is initiatively to anchor point network element announcement access network load information;
The anchor point network element provides mobile management services such as quick switching, stream migration according to the terminal interface state information, terminal positional information, access network load information, the Business Stream strategy that obtain from many interfaces multiple access server for the user.
When carrying out Business Stream policy distribution flow process as shown in Figure 6; Issuing of Business Stream strategy can comprise two processes: the terminal obtains the Business Stream strategy from many interfaces multiple access server, and the anchor point network element obtains the process of Business Stream strategy from many interfaces multiple access server.
Wherein, step 1 and step 2 have been described the policy download process that initiate at the terminal.This process can define new message separately, also continues to use the existing network access process, and the new particular community of definition is used for the requested service Flow Policy in existing message;
Particularly, step 1.1: mobile node requested service Flow Policy, send Business Stream strategy request message to access device.Comprise ID in the said Business Stream strategy request message;
Step 1.2: after access device was received Business Stream strategy request message, the Business Stream strategy request of redispatching message is interface multiple access server at the most;
Step 2.1: after many interfaces multiple access server is received the request message that comes from access device,, issue about this user service flow strategy to access device according to the ID of carrying in the message;
Step 2.2: access device with the user traffic flow policy distribution to MN.
In the step 3, when the Business Stream strategy changes, many interfaces multiple access server also can the active push services Flow Policy to portable terminal.For example server initiatively sends the access device of Business Stream strategy to the current place of user, and this access device is sent to MN with the Business Stream strategy of receiving;
In step 4 and the step 5, the anchor point network element is after user's registration, to many interfaces multiple access server requests user service flow strategy.Business Stream strategy on the anchor point network element need be consistent with the Business Stream strategy on the MN.
